A '''local shared object''' ('''LSO'''), commonly called a '''Flash cookie''' (due to its similarity with an [[HTTP cookie]]), is a piece of data that websites that use [[Adobe Flash]] may store on a user's computer.

Flash cookies, which can be stored or retrieved whenever a user accesses a page containing a Flash application, are a form of local storage. Similar to cookies, they can be used to store user preferences, save data from [[Flash game]]sgames, or track users' Internet activity.<ref>[https://www.theguardian.com/technology/2014/oct/05/cookies-crumbled-internet-anonymity The Guardian newspaper, When the cookies crumbled, so did your web anonymity, 5 October 2014]</ref> LSOs have been criticised as a breach of [[browser security]], but there are now browser settings and addons to limit the duration of their storage.
